The experts at the University of Southern California (USA) have developed a technique towards creating a stable solar batteries and cheap from the nanocrystal size is only 4 nanometers (1 nanometer = 1 billionth meter).

The crystals are so tiny that they can exist in liquid form and used to paint ink or printed onto the flat surface, such as windows, walls and roof. "Like in a newspaper, you can print solar battery", Associate Professor Richard L. Brutchey, team members explained. The manufacture of liquid solar battery is said to be cheaper than solar batteries using silicon materials to the current application which is not very effective in converting sunlight into electricity. The new technique may allow us to print on plastic instead of glass without worrying about the molten state, thereby creating a flexible solar panels can be installed anywhere. "But this technology takes many years to commercialize, we found most promising in its application to solar cell technology generation," said Brutche
Meanwhile, the other team is also working on similar technology; including the use of nanocrystals to create solar coating can absorb energy and generate electricity. For example, scientists at the University of Notre Dame (USA) have used the molecular with nanoscale titanium oxide and embed them in a solution of cadmium sulphide or cadmium selenide. When we mix all the things of water and alcohol, they form dough. Continuing to paint this paste onto a conductive material and sunlight in, scientists noticed it had to produce electricity. Although electricity generated only by one tenth compared to current solar pin, but scientists believe it will soon help improve capacity and promises to turn the house into optical power station technology. Paint of solar energy may be present in the market for several years. |
